The first free-living organism to have its genome completely sequenced was the bacterium Haemophilus influenzae, in 1995.
In 1996 Saccharomyces cerevisiae (baker's yeast) was the first eukaryote genome sequence to be released and in 1998 the first genome sequence for a multicellular eukaryote, Caenorhabditis elegans, was released.
